Steel Cord Conveyor Belt Description

As conveyor systems become longer and handle larger volumes and tonnages, the conveyor belt itself needs to become stronger. Compared with fabric, steel cord conveyor belt has higher strength and lower elongation. The steel cord conveyor belt provides cheaper and more reliable performance for any long-distance or high-lift system.

Baoxiang steel cord conveyor belt is excellent for long-distance, high abuse and demanding applications. The high durability brought about by the excellent joint efficiency, and the tight bond between the steel rope and the rubber can achieve a longer service life even under harsh conditions .You can contact us for detailed information and quotation!

Steel cord conveyor belt construction

Steel cord conveyor belts have high wear resistance and are mainly used for long-distance transportation, heavy loads and occasions that require high physical strength. They are particularly suitable for high mass or volume flow and abrasive materials.

1- Coverage level.

Steel cord conveyor belt has a variety of coverage levels, all made of high-quality rubber, with high abrasion resistance, cut resistance and impact resistance, as well as excellent aging properties. The choice of coverage level depends on the application and will also determine the service life of the steel cord conveyor belt.

2- (Optional) Embed other reinforcing materials in the unvulcanized core rubber. It is applied like the second core rubber sheet.

3- Core rubber sheet.

4- Steel cord conveyor belt adopts original core rubber.

It is made of high-strength steel wire rope and various covering grades. A typical carcass with 7 x 7 hot-dip galvanized steel cords can provide a tensile strength of up to 2,000 N/mm. 7 x 19 can also be used for higher tensile strength (10 000 N/mm).

The elongation of the standard cord is 0.22-0.28%. The high structural strength and tensile strength ensure good fatigue resistance. The cord's open cross-lay design and chemical adhesive system ensure thorough penetration of the core rubber, good adhesion and long-term integrity of corrosion protection.

5- The middle rubber strip.

Resistance

Provide abrasion resistance, heat resistance and flame retardant grades.

Wearable

Available in X, Y, W grades (and similar grades), suitable for heavy abrasion transportation applications, such as bulky, sharp materials, such as heavy, abrasive rocks. It is recommended to use a high-quality coverage level to provide the best protection for the belt.

Heat resistant

Different types of grades are available for high temperature applications (T120 and T200), such as clinker, coke, foundry sand and slag. Can be used to transport materials at continuous temperatures up to 190 °C, with peaks up to 200 °C

Flame retardant

Provide flame retardant grade K in accordance with ISO 340. Can be used for tunnel projects, but not for underground applications.

Wire Rope Core Conveyor Belt Features

High tensile strength, good impact resistance, long life, small use elongation, good groove, good flexure resistance. Suitable for long-distance, large volume and high-speed transportation of materials. The steel cord conveyor belt is composed of core glue, wire rope, covering layer and edge glue.

high strength

If the operating tension of the belt must be higher than 2500 KN/m, steel rope reinforced belt is the only option. There is a steel cord conveyor belt with a rated output power of up to 10,000 KN/m. Steel cord belts are also an economical alternative to fabric belts with a value between 1000 KN/m and 2500 KN/m.

Lower safety factor

The safety factor of the cloth belt design is 10, while the safety factor of the steel cord conveyor belt is only 6.67. This means that wire rope belts with lower ratings can be used instead of fabric belts, saving the life of the operator.

Shorter winding

The elongation of a material depends on its elastic modulus. And the superior elastic modulus of steel cord; the elongation can be less than 0.25%; this can shorten the winding length.

Long center spacing

The stretch of steel cords is much smaller than that of woven fabrics, and in addition to strength, the belt can also be designed with a long pulley pitch. There are fewer restrictions on pick-up and transfer points.

Smaller pulley diameter

Due to the thinner carcass than the same type of fabric belt, the steel rope belt can run on a smaller diameter pulley, thereby saving energy. Since the dynamic modulus of steel is better than that of fabric, the fatigue is much lower.

High impact resistance

Compared with textile conveyor belts, the structure of steel core belts usually results in a higher proportion of rubber in the entire belt. The extra rubber means that the belt can better absorb impact energy. For all applications where heavy objects may suddenly appear, steel rope straps are a good choice.

Excellent passability

Even the highest-rated wire rope belts are very suitable for low-lying areas. This ensures easy training of the belt and gives the belt a greater effective capacity. This allows users to increase throughput or use a narrower frequency band.

Long life expectancy

The steel cord belt can provide a thinner carcass and thicker covering rubber, and has the same grade as the same fabric belt. Thereby increasing the belt life. The carcass also has a longer life than the same fabric carcass.

Joint life and strength

If provided properly, the life of the belt is as long as the belt itself. You can also achieve a splicing strength that is almost 100% of the strap strength.

Easy to repair

The wire rope belt can be repaired by hot vulcanization or cold vulcanization, and the damaged edge can be restored to its original width by hot repair. The worn cover can be replaced with fresh rubber that is durable enough to fully rejuvenate the belt and make the customer more economical.

Steel cord pipe conveyor belt application

Widely used in coal, mine, port, metallurgy, electric power, chemical industry and other fields to transport materials.
